Example 1 with PermissionEvaluator

use of org.keycloak.authorization.permission.evaluator.PermissionEvaluator in project keycloak by keycloak.

the class PolicyEvaluationTest method testCheckReadOnlyInstances.

public static void testCheckReadOnlyInstances(KeycloakSession session) {
    session.getContext().setRealm(session.realms().getRealmByName("authz-test"));
    AuthorizationProvider authorization = session.getProvider(AuthorizationProvider.class);
    ClientModel clientModel = session.clients().getClientByClientId(session.getContext().getRealm(), "resource-server-test");
    StoreFactory storeFactory = authorization.getStoreFactory();
    ResourceServer resourceServer = storeFactory.getResourceServerStore().findByClient(clientModel);
    JSPolicyRepresentation policyRepresentation = new JSPolicyRepresentation();
    policyRepresentation.setName("testCheckReadOnlyInstances");
    StringBuilder builder = new StringBuilder();
    builder.append("$evaluation.getPermission().getResource().setName('test')");
    policyRepresentation.setCode(builder.toString());
    Policy policy = storeFactory.getPolicyStore().create(policyRepresentation, resourceServer);
    Resource resource = storeFactory.getResourceStore().create("Resource A", resourceServer, resourceServer.getId());
    Scope scope = storeFactory.getScopeStore().create("Scope A", resourceServer);
    resource.updateScopes(new HashSet<>(Arrays.asList(scope)));
    ResourcePermissionRepresentation permission = new ResourcePermissionRepresentation();
    permission.setName("testCheckReadOnlyInstances permission");
    permission.addPolicy(policy.getId());
    permission.addResource(resource.getId());
    storeFactory.getPolicyStore().create(permission, resourceServer);
    session.getTransactionManager().commit();
    PermissionEvaluator evaluator = authorization.evaluators().from(Arrays.asList(new ResourcePermission(resource, Arrays.asList(scope), resourceServer)), createEvaluationContext(session, Collections.emptyMap()));
